After a lot of tries, I figured out how to install windows 10 on my raspberry from a windows 8.1 VM: Hardware: USB reader. 16 GB micro SD card. Raspberry PI 2 Installation Steps: Install windows 10 ADK technical preview (https://go.microsoft.com/fwlink/p/?LinkId=526740) on windows 8.1 VM. Navigate to the installation folder which in my case was “C:\Program Files (x86)\Windows Kits”, then navigate to 10\Assessment and Deployment Kit\Imaging and Configuration Designer\x86 Run ICD.
